Quality Level and Price in Turkish Durum Wheat Market

This study has been made to assess the influences and effects of durum wheat quality characteristics on the prices in Turkish durum wheat market. The current prices are determined as the result of the applied analysis, in respect to the quality characteristics of durum wheat. The Turkish durum wheat varieties are compared with the wheat varieties of other countries, from where Turkey is importing durum wheat in respect to the quality characteristics. It has been assessed that hectoliter and glassware are the major factors that have the greatest effect and influence on Turkish durum wheat market in respect to the quality aspects.     

Testing for spatial market integration and law of one price in Turkish wheat markets

This paper examines co-integration models in testing for spatial market integration and the Law of One Price (LOP) for Turkish wheat market. The multivariate co-integration tests show that there is one co-integrating vector in the system which implies that though the markets are integrated, the LOP does not hold. Vector error correction model restrictions tests also show that structural breaks have impacts on the long-run linkage among the prices. These results are important for wheat production policies and for wheat market liberalization considerations in the future.     

Sunn Pest Control Policies and Effect of Sunn Pest Damage on Wheat Quality and Price in Turkey

Wheat is a very strategic crop for Turkey as well as many other countries. Sunn pest is one of the most important pests of cereals particularly for wheat and barley in Turkey. Turkish governments have conducted sunn pest management (SPM) program, mainly based on chemical control since 1927. Neither farmers nor technical consultants have been satisfied with the SPM program conducted by the government. Therefore, the government purpose is to transfer SPM program to the farmers by providing technical information and equipments gradually. In this paper, effect of sunn pest damage on wheat price in Turkey is analyzed by using hedonic price function. The results show that sunn pest damage is the most effective factor and causes a significant decrease in wheat prices.     

A Test for a Functioning Market Economy: Seton'S Eigenprices of Turkey

We use Seton's eigenprices to see if some evidence can be found in support of the European Commission's official statement that the Turkish economy can be considered as a functioning market economy. Given an input–output flows matrix, there is a unique set of prices for outputs and production factors compatible with final demand, generating demand for factors. The findings based on Turkey's most recent I–O table and comparable I–O matrices for Romania and Poland (two EU members) in 2005 show that price distortions were on average five times larger in Turkey. Hence, based on price distortions alone, there was no solid evidence in support of the statement that Turkey had a functioning market economy.     

Dynamic competition with consumer inertia

We study a framework where two duopolists compete repeatedly in prices and where chosen prices potentially affect future market shares, but certainly do not affect current sales. This assumption of consumer inertia causes (noncooperative) coordination on high prices only to be possible as an equilibrium for low values of the discount factor. High discount factors increase opportunism and aggressiveness of competition to such an extent that high prices are no longer sustainable as an equilibrium outcome. Moreover, we find that both monopolization and enduring market share and price fluctuations (price wars) can be equilibrium path phenomena without requiring exogenous shocks in market or firm characteristics.     

TIME IS OF THE ESSENCE: THE IDEA OF THE COROLLARY OF THE COASE THEOREM AND A POSSIBLE APPLICATION

Extant theories on the application of the Coase Theorem to the development market have focused on the effects of zoning on the environment or upon property prices. As an original contribution to the Coasian research on the interface between the development market and the statutory planning machinery, this article seeks to develop a Coasian proposition informed by what has been called the corollary of the Coase Theorem, which allows for an empirical examination of the impact of property prices on decisions to use resources under different institutional arrangements. Our proposition is that the procedural steps taken to consume resources are not contingent on property prices unless the associated transaction costs are positive or property rights ambiguous.     

Keeping a weather eye on prediction markets: The influence of environmental conditions on forecasting accuracy

Increasingly, prediction markets are being embraced as a mechanism for eliciting and aggregating dispersed information and providing a means of deriving probabilistic forecasts of future uncertain events. The efficient market hypothesis postulates that prediction market prices should incorporate all information that is relevant to the performances of the contracts traded. This paper shows that such may not be the case in relation to information regarding environmental factors such as the weather and atmospheric conditions. In the context of horserace betting markets, we demonstrate that even after the effects of these factors on the contestants (horses and jockeys) have been discounted, the accuracy of the probabilities derived from market prices is affected systematically by the prevailing weather and atmospheric conditions. We show that significantly better forecasts can be derived from prediction markets if we correct for this phenomenon, and that these improvements have substantial economic value.     

Determinants of house prices in Istanbul: a quantile regression approach

This paper uses quantile regression methods where a hedonic equation is estimated for each quantile of the conditional distribution of housing prices. The survey data are used to investigate the relationship between house prices and housing characteristics in Istanbul. This data set includes some housing characteristics of the dwellings like numbers of room, bathroom, heating system, location of house etc. In the results of this paper show some similarities and differences from earlier studies on housing prices. We find that age, cable tv, security, heating system, garage, kitchen area, increasing numbers of room and bathroom increase the house prices. Our findings also show that side variable which is a special factor for Istanbul real estate market has negative effect on the prices. It is clear that the factors of housing prices can change because of the properties of country, region or city. The results of this study may give some important interpretations for developing real estate market.     

On illiquidity of an emerging sovereign bond market

This study offers an analysis of a sovereign bond market in an emerging country, Turkey, and its illiquidity. We employ the Nelson-Siegel model to generate a term structure for interest rates directly from daily bond price quotes in the Turkish market. We take the noise measure, which is the byproduct of term structure estimation, as a proxy for market-wide illiquidity. Our results show that this noise measure can capture the illiquidity in the Turkish fixed-income market from global financial turbulence as well as local dynamics. Inflation uncertainty and sentiment are the major macro drivers of liquidity crunches. It has also become clear that liquidity in an emerging market such as Turkey in the aftermath of the 2008 crisis has been driven by global forces, however, since 2013 local factors have taken over. This apparent decoupling in liquidity between a major emerging market and global markets followed the approaching end of quantitative easing and a rise in economic turbulence in the country since then.     

Production quality and pricing strategy for substitutable products under comparison effects

Comparison effects have been studied extensively in many fields. In particular, existing operations management articles have discussed the impact of comparison effects on enterprises' production and pricing decisions. Research has also shown that consumers' purchasing decisions are primarily determined by three factors: product quality, selling price, and comparison effects. The current study introduces the concepts of social and temporal comparison effects to examine how comparison effects influence a monopolist’s production quality and pricing strategy for substitutable products. Results reveal the following: (1) Setting different prices for even two types of substitutable products with negligible quality differences can divide customers into three groups under the influence of social comparison effects in a single-stage model. (2) The monopolist should avoid using a price discrimination strategy in which products with a short market life cycle have the same quality but different prices. (3) When the market life cycle of products is sufficiently long in the single-product market and the market with two substitutable products, the monopolist’s optimal choice in the second stage is to keep production quality constant and increase the selling price. Consequently, the number of buyers does not decrease because of temporal comparison effects. Therefore, the firm increases its revenue. (4) For the market with two substitutable products with quality differences, one approximate optimal strategy for the enterprise in the second stage is to keep the selling price constant with the assumption that product quality cannot be adjusted after the first period. At this point, the consumption situation in the market is the same as that in the first stage. Therefore, when no external constraints exist, the monopolist firm can obtain more benefits in the second stage than in the first stage by exploiting the temporal comparison effects of consumers in the second stage. (5) When consumer identity information can be confirmed in the market, social comparison effects, similar to temporal comparison effects, could help the enterprise increase its price and profit while maintaining product quality. These social and temporal comparison effects constrain consumers. Thus, the number of people who continue to buy products does not decrease.     

Intercompany mobbing: the effects of company growth

Exploring the concept of mobbing, we have conducted a study of small and middle sized enterprises (commonly referred to as SMSE). In this study we observed corporate policies of repression and intimidation while taking into consideration the aim of these policies and their possible consequences. The ultimate purpose of this work is to shed light onto forthcoming academic studies of the same topic. Our focus has been the effects of the various presses, forms of harassment and market entry prevention carried out by companies that dominate the market against those companies entering the market and those already competing in the market. To determine these effects on 150 companies that conduct business in Turkey, we created a survey consisting of 15 categories. The results have been depicted with charts and graphs. The conclusion of the investigation has found that many of the attitudes which comprise of mobbing acts can be seen in the mutual behavior of the companies that work in the Turkish labor market. Although there are a number of reasons for the prevalence of the mobbing culture in Turkish business, it’s our belief that the Turkish labor market codes of conduct and regulations influence the perpetuation of ruthless behaviors between different companies.     

Permanent and transitory shocks in owner-occupied housing: A common trend model of price dynamics

Significant fluctuations in house prices have received considerable attention in recent years. An understanding of the forces underlying the departure from fundamental values is important in explaining the mechanisms underlying housing market performance and predicting potential house price changes in the future. This study constitutes the first use of a common trend (CT) model to analyze private house prices in the Swedish market. We employ a cointegration system to analyze the macro variables of consumption expenditure per capita, user costs and house prices. We decompose shocks into those resulting from fundamental variables, specified in this research as income and the interest rate, and those resulting from cyclical variables. The results indicate that interest rates play a dominant role in explaining house price swings, and are also significant in determining user costs for households in Sweden. Transitory shocks are found to have little explanatory power for house prices and user costs in the long run. A number of tests have been performed to verify the robustness of the specification and results.     

Market Implications of the Audit Quality and Auditor Switches: Evidence from China

Independent audits enhance the credibility of corporate financial reports and assist investors to make rational decisions in the capital market. Nonetheless, the utility of the auditing function depends upon the quality of audits, which is determined by the independence and expertise of auditors. Hence, auditor choice and switch will not only affect an audit's quality, but will also influence decisions made by investors and other market participants. The purpose of this paper is to investigate how investors respond to the quality of audits and auditor switches in the Chinese context. Empirical results show that the quality of an audit and switching to a larger auditor have a positive (negative) impact on earnings response coefficients (ERCs) for firms with positive (negative) abnormal earnings. In contrast, switching to a smaller auditor has a negative (positive) impact on ERCs for firms with positive (negative) abnormal earnings. These results suggest that large auditing firms (Top 10) in China are perceived as more effective for curbing income-increased earnings management, which leads to higher (lower) ERCs for clients with positive (negative) abnormal earnings. Firms' switching to a larger auditor may signal high-quality earnings. Therefore, investors more often increase stock prices when firms have positive abnormal earnings and less often depreciate prices for negative abnormal earnings. Similarly, switching to a smaller auditor may signal lower earning quality, resulting in opposite market responses. In general, the empirical evidence suggests that audit information is valued by the capital market in China. Large auditing firms have been able to product-differentiate themselves within the Chinese stock market.     

TOWARDS A SYNTHESIS OF ISLAM AND THE MARKET ECONOMY? THE JUSTICE AND DEVELOPMENT PARTY'S ECONOMIC REFORMS IN TURKEY

Turkey has some unique characteristics, one of which is that it is the only Muslim country seeking to join the European Union. Internally, it has been going through a new and challenging experience in recent years: implementing free-market economic policies under a 'Conservative Democrat' government, the leadership of which comes from moderate Islamism. Many observers think that Turkish experience shows how Islam and the market economy are compatible. This article critically evaluates these reformist economic policies implemented since late 2002 and highlights the major factors behind Turkey's success story.     

New insights into the role of global factors in BRICS stock markets: A quantile cointegration approach

Because of the acceleration in marketization and globalization, stock markets in the BRICS (Brazil, Russia, India, China, and South Africa) countries are affected by various global factors, for example, oil prices, gold prices, global stock market volatility, global economic policy uncertainty, financial stress, and investor sentiment. This paper offers new insights into the short- and long-run linkages between global factors and BRICS stock markets by applying the quantile autoregressive distributed lags (QARDL) approach. This novel methodology enables us to test short- and long-run linkages accounting for distributional asymmetry. That is, the nonlinear dynamic relationship between the global factors and BRICS stock prices depends on market conditions. Our empirical results show that the effects of gold prices and global stock market volatility on BRICS stock prices are more significant in the long run than in the short run. A decrease in global stock market volatility is associated with higher stock prices, while gold prices demonstrate upward co-movement in dynamic correlations with stock markets. Irrational factors, such as economic policy uncertainty, financial stress, and investor sentiment, play a critical role in the short term, and negative interdependence is dominant. Finally, the rolling-window estimation technique is used to examine time-varying patterns between major global factors and BRICS stock markets.     

The influence of racial segregation on housing prices

Census tract data were used to investigate the influence of racial segregation on housing prices in the Oakland, California housing market. White renters were found to pay a premium to live in segregated neighborhoods. Racial differences in the implicit prices of specific housing characteristics were also observed in the rental market: a unit of housing space was more expensive in the black rental submarket, while a unit of housing quality cost more in the white rental submarket. No significant differences were found in the prices paid by black and white homeowners, although for methodological reasons these results were less reliable than those for rental housing.

The economic and financial properties of crude oil: A review

In this article, we provide a structured review of crude oil price dynamics. Specifically, we summarize evidence on important factors determining oil prices, cover the impact of oil market shocks on the macro economy and the stock market, discuss how the financialization of crude oil markets affects oil market functionality and efficiency, and we then outline approaches for forecasting crude oil prices and volatility. By comparing the results of the most influential early contributions and recent studies, we can identify important developments and research gaps in each field. Thus, our review provides academics and practitioners newly engaging in crude oil research with an overview of what scientists know about crude oil dynamics and highlights which topics areparticularly promising for future research.     

Comparative empirical study of binomial call-option pricing methods using S&P 500 index data

In this paper, several binomial models are tested empirically on S&P500 Index on the levels of tradability, proximity to market (RMS) prices and profitability, especially close to expiration day. These comparisons will be carried out for many different business environments, including different market trends and moneyness levels traded. Among the models under analysis we assess the quality of the SH model, developed by the authors in previous work, in relation to other models. The option price in the SH model is affected by the players’ assessments about the behavior of the prices of the underlying asset up to the expiration day and by their “eagerness” levels (i.e., players’ readiness to respond to a given bid proposed by their opponent). We found that for all models, the higher the moneyness, the greater the proximity of models prices to actual market prices and that, eagerness parameters have a decisive effect on tradability. We also found that there was no correlation between the degree of proximity of modeled prices to actual prices and the expected profit gained by players that act according to a given model and that the SH model traded relatively small number of options. The expected profit is highest for the SH model in the ITM and ATM for days that are far from the expiration day.     

The relationship between accounting numbers and returns: some empirical evidence from the emerging market of the Czech Republic

Generally, stock prices reflect future expectations of earnings, whereas accounting data reflect past performance. This paper attempts to discover the relationship between accounting data and market price returns of the companies listed on the Prague Stock Exchange (PSE). The Prague Stock Exchange was established in 1993 and provides an opportunity to make a comparison between a newly established market and the findings of studies of established markets. There has been a wealth of publications and accounting research studies on developed markets. Generally, accounting attributes are thought to be relevant because they tend to be contemporaneously statistically associated with stock prices. Some studies have suggested, and empirically tested, that stock prices lead earnings (e.g. Collins et al., 1987; Kothari, 1992; Kothari and Sloan, 1992; Kothari and Zimmerman, 1995). This study tests the existence of such a relationship in the Czech capital market, relying partially on the methodology proposed by Kothari and Sloan (1992) and Kothari (1992). This paper investigates whether there is a statistically significant permanent relationship between returns and accounting data on the Czech market. The study was conducted using accounting earnings and stock prices during the period 1993–8. The empirical evidence here suggests that a similar relation exists on the emerging Czech market. The relation is statistically significant for measurement windows of one year and longer. The increase in the mean response coefficient, reported later in this study, suggests that one-leading-year returns are as important as contemporaneous returns in terms of their sensitivity to annual earnings changes. However, one cannot infer with a degree of confidence that the Czech capital market views earnings changes to be largely permanent, which would be consistent with the time-series properties of annual earnings.
